I'm on Ubuntu 8.04 (Hardy Heron), and using Eclipse 3.2.2. I can compile other C code just fine (having a great time w/ GTK+). I can see that usb.h is in my `Includes` folder i.e., `/usr/include/usb.h` but I get a bunch of messages when I attempt to compile like:

undefined reference to `usb_init'

I guess it is something to do w/ the Linker as that is where the error gets thrown (see below). But how would I go about resolving that?
